Significance and actual status of the dissection of paraaortic lymph nodes in the cases with gastric cancer.
The results of the surgical resection of the paraaortic lymph nodes metastases of the gastric cancer were evaluated in 116 cases. The frequency of the dissection of paraaortic lymph nodes (No. 16 lymph node) was 20%; the metastatic ratio was 24%. When classified by regions, the highest frequency of metastasis was observed in the cases of upper gastric cancer. The effect of the dissection of No. 16 was more conspicuous when No. 16 metastases were absent than when No. 16 metastases were present. Particularly, the prognosis was improved in the case of n1 and n2 population of the cases which were positive with respect to the proximal lymph node metastasis. It appears altogether that the dissection has considerable significance as prophylactic treatment.
